Periodic maintenance
Suction head in the fuel tank
N
21
STOP
The felt filter (N/21) of the suction head is used to filter the fuel
taken in by the carburetor.
A periodical visual inspection of the felt filter should be con-
ducted. For this purpose open the tank cap, and use a wire
hook to pull out the suction head through the tank opening. If
the filter has hardened or is dirty or clogged, replace it (see
"Excerpt from the spare-parts list").
Insufficient fuel supply can result in the admissible maximum
speed being exceeded. It is therefore important to replace the
felt filter at least every three months to ensure a good fuel
supply to the carburetor.
STOP Muffler guard
O
Check if the muffler guard (O/22) is in good condition. A bent,
broken or missing muffler guard can cause bush fires especi-
ally during dry weather conditions.
Replace a non-functional muffler immediately!
Also check the four clamp rings (O/23) before using the
brushcutter. Replace damaged clamp rings immediately! The
correct mounting and positioning of the muffler is essential to
guarantee protection against a possible fire hazard from the
engine exhaust.

Shutting down procedure and storage
If you are not planning to use the brushcutter for a period in excess of 6 weeks, it is recommended to observe the following
instructions:
• Perform the servicing operations as described on pages 18 to 24.
• Empty the fuel tank and run the engine until the carburetor is dry. Fuels have only a short storage life and can cause sedimentary
deposits in the fuel tank or carburetor.
• Remaining fuel in canisters should be used for other engines, or properly disposed of.
• Clean and lightly lubricate metallic cutting tools.
• Store the brushcutter in a dry place only.
• The next time you use the brushcutter, purchase new fuel and prepare the two-stroke mixture as specified.
Information about the gear box
P
24
The gear box (P/24) is provided with a permanant lubrication
and consequently does not need any maintenance.
However, if large quantities of grease are leaking from the
gear box, consult a DOLMAR service station.
Servicing and maintenance
We recommend that a comprehensive maintenance and in-
spection be performed at regular intervals.
Any maintenance or adjustment work not described in this
manual may be performed only by a DOLMAR service sta-
tion.
